        WORKS FOR ALL S550

        Don’t listen to Americanmuscle. This works perfectly fine for all S550s. No issue at all. They just seem kinda lazy and refuse to test if products from 15-17 work on the 18 . Kinda sad. I don’t buy from this company unless they are the only ones offering the parts anymore.

        Gotta match the GT350 steering wheel

        I have the GT350 steering wheel, so adding this GT350 start button was a nice detail. During install, needed 2 small screw drivers to pop off original, but came off fine to preserve for future, just in case.

        Nice touch to the interior

        Was a little bit challenging to get off but persistence paid off. I was afraid of cracking the interior components but did not. I just kept gently working and prying on it . Use a set of picks. Place plenty of blue painter's tape all around the button to protect from scratches as I did slip a few times luckily I had the tape. Also wrap the tips of the Pik with electrical tape to protect from scratches

      whats the difference between the buttons m10b776-mr and 394094

      • They work the same way and do the same thing, however, the ford performance m10b776-mr is the ford factory replacement part.

      2019's are out. The 2018's have been out for over a year. Please check fitment for 2018's so we know for sure.

      • The current version of the Modern Billet GT350/GT350R Style Red Push Start/Stop Button is not compatible with 18-19 Mustangs.

      I installed this but I just noticed the left side is loose and sticks out a bit. Do you know what is wrong/how I can fix it? Thank you

      • We would advise to re position the button and make sure that it is firmly and securely pressed back on the Engine Start/Stop area. If this is causing further issues with sticking out please reach out directly to our customer service department as we would be glad to work with you here to make sure that this is installed properly. You can reach us either by giving us a call at 1-877-887-1105 or by chatting in with our live chat support team.

      The factory GT350 button cover is plastic. This one is actually billet?

      Why doesnt this work with a 2019 GT? Will we ever get one?

      • This does not fit 2018+ GT models due to physical differences in button setups. We are not aware of plans to make a model for 2018+ models at this time.
